EMERGENCY NURSINGRoberto M. Salvador Jr. RN MD

Is a specialized education, training and experience to gain expertise in assessing and identifying patients health care problems in crisis situations.

Emergency nurse establish priorities, monitors and continuously assesses acutely ill and injured patient’s, supports and attends to families, supervise allied health personnel and teaches the patient and families within a time limited, high pressured care environment.

Issues in Emergency Nursing Care1. Documentation of consent.2. Limiting exposure to health risk.

Providing holistic care a. Patient focused intervention b. Family focused intervention 1. Anxiety and denial 2. Remorse and guilt 3. Anger 4. grief

Helping family members cope Take the family members to a

private place Talk to the family together Reassure the family that everything

possible was done Encourage family members to

support each other Encourage the family to view the

body if they wish Spend time with the family

members, listening to them and identifying any needs

Avoid unnecessary information

Care given to clients with urgent and critical needs

Care must be rendered without delay

Diversified situations Consent (unless unconscious and

without S.O.) Common clients (elderly, stomach

pain, chest pain, fever, drug related, wound)

Disaster Nursing (terrorism)Principle: TRIAGE

Triage - a process use in sorting victims into categories of priority for care and transport based on severity of injuries and medical emergencies.

TRIAGEFrench word “trier” to sortSorting of clients based on the severity of health problemsHierarchy based on the potential for life lossAdvanced skills

Principles of tactical triage1. Accomplish the greatest good for

the greatest number of casualties2. Employ the most efficient use of

available resources3. Return personnel to duty as soon

as possible

TRIAGE3 categories of TRIAGE (Berner’s)

1. Emergent2. Urgent3. Non-urgent

TRAUMAStab Wound1. Intra-abdominal injuries:

Penetrating abdominal injuries Gunshot wound, Stab wounds Serious & requires surgery Liver ( most frequently injured solid

organ) All abdominal gunshot wounds

require surgical exploration Stab wounds may be managed

non-operatively

Blunt TraumaBlunt Abdominal Injury

Result from motor vehicle crashes, falls, blows or explosions

Injuries may be hidden or difficult to detect

Involves the liver, kidneys, spleen, blood vessel

Page 5: Emergency Nursing

Assessment & Diagnostic Findings History & PE Lab studies: Urinalysis serial Hct. level WBC count Serum amylase analysis

Internal Bleeding Inspection ( front of the body,

flanks & back) Bluish discoloration, asymmetry,

abrasion, contusion Abdominal CT Scan Abdominal Ultrasound Left shoulder pain ( ruptured

spleen) Right shoulder pain (liver

laceration)

Intraperitoneal Injury Assess for tenderness, rebound

tenderness, guarding, rigidity, spasm, increasing distention &

pain Referred pain ( intraperitoneal

injury)

Diagnosis:1. abdominal ultrasound2. abdominal CT scan3. Diagnostic peritoneal lavage 1 L LRS/ NSS 400 ml return RBC > 100,000/mm3 WBC ct > 500/mm3 Bile, feces, food

Sinography ( detection of peritoneal penetration)

Intraabdominal Injury Management: Resuscitation procedure Occlusion of chest wound Direct pressure Intravenous fluid replacement Immobilization of the spine Cervical spine immobilization Tetanus prophylaxis Broad spectrum antibiotics

Multiple Casualty Incident

MCI is defined as an event involving a number and/or severity of casualties,which is beyond the capabilities of available care teams and facilities.

MINIMAL (GREEN TAG) Also known as the “walking

wounded” Examples include but are not

limited to – small burns, lacerations, abrasions, and small fractures.

These casualties have minor injuries and can usually care for themselves with self-aid or “buddy aid”. These casualties should still be employed for mission requirements (e.g., scene security).

DELAYED (YELLOW TAG) The delayed category includes

wounded casualties who may need surgery, but whose general condition permits a delay in surgical treatment without unduly endangering life or limb. Medical

Page 6: Emergency Nursing

treatment (splinting, pain control, etc.) will be required but it can wait.

Examples include but are not limited to – casualties with no evidence of shock who have large soft tissue wounds, fractures of major bones, intra-abdominal or thoracic wounds, or burns to less than 20% of total body surface area.

IMMEDIATE (RED TAG) The immediate category includes

casualties who require immediate LSI and/or surgery. Put simply, if medical attention is not provided, the patient will die. The key to successful triage is to locate these individuals as quickly as possible.

Examples include but are not limited to – hemodynamically unstable casualties with airway obstruction, chest or abdominal injuries, massive external bleeding, or shock.

EXPECTANT (BLACK TAG) Casualties in this category have

wounds that are so extensive that even if they were the sole casualty and had the benefit of optimal medical resources, their survival would be highly unlikely. Even so, expectant casualties should not be neglected. They should receive comfort measures, pain medications, if possible, and they deserve re-triage as appropriate.

Examples include but are not limited to – casualties with penetrating or blunt head wounds and those with absent radial pulses.

TRIAGE TAGS Triage tags are designed to

communicate the triage category, treatment rendered, and other medical information. By necessity, the information on the tag is brief. Triage tags are usually placed on the casualty by the triage officer although other members of the team may place or add information to the tags.

PURPOSE To furnish the attending care

provider during the evacuation of a casualty with essential information about the injury or disease and the treatment provided.

The sole or initial medical record for the troops injured in combat.

Each triage tag is coded with a unique sequential seven-character serial number used for identification and tracking of the casualty. The serial number is located on the top right and left diagonal tear-offs.

Management: Determine the extent of injuryEstablish priority of treatmentNursing management in Sprain, Strain:1. Immobilize extremity and advise rest2. Apply cold packs initially then heat packs3. Compression bandage may be applied to relieve edema4. Assist in cast application5. Administer NSAIDS

FRACTURE

Page 7: Emergency Nursing

A fracture is a complete or incomplete break in the continuity of bone. This will be accompanied by varying degrees of injury to surrounding soft tissues.

CLASSIFICATION OF FRACTURESBROAD CLASSIFICATION1. Complete fractureInvolves a break across the entire cross-section of the bone & is frequently displaced 2. Incomplete fracture (usually in adults)The break occurs through only a part of the cross-section of the bone

Break in the continuity of the bone cause: DISPLACEMENT OF FRAGMENT CAUSES: DAMAGE TO THE SOFT PART CAUSES:

Clinical Features of Fractures: 1) pain and tenderness over the involved area 2) loss of function 3) deformity 4) attitude ( shortening) 5) abnormal mobility and crepitus (a grating sensation produced when bones rub each other) 6) neurovascular injury ( localized swelling & discoloration of the skin) 7) radiographic findings

EMERGENCY MANAGEMENT OF FRACTURE1. Immobilize any suspected fracture by splinting

2. Support the extremity above and below when moving the affected part from a vehicle 3. Suggested temporary splints- hard board, stick, rolled sheets4. Apply sling if forearm fracture is suspected or the suspected fractured arm maybe bandaged to the chest5. Open fracture is managed by covering a clean/sterile gauze to prevent contamination6. DO NOT attempt to reduce ( re-align) the fracture

5 P’s in Fracture:P – painP – pallorP - paresthesiaP - pulselessnessP - Paralysis

Nursing ConsiderationsAssessA airwayB breathingC circulation neurogenicD disabilityE expose

“always IMMOBILIZE the affected bone” Principles of Fracture Treatment

1. Reduction of fracture 2. Maintenance of alignment 3. Promote callus formation4. Restoration of function 5. Prevent complications

6. Wound care7. Diagnostic and Lab Procedures8. Fracture Reduction

Compartment Syndrome - a condition in which the circulation and function of tissues within a closed space are compromised by an increased pressure within that space S/Sx: 4 Ps - Pain / Pallor / Paralysis / Pulselessness * although none is pathognomonic, pain is the most important * best indicator: tissue pressure measurement - a surgical emergency (fasciotomy) Whitesides Technique * for measuring intracompartmental pressure * results in permanent neurovascular damage if not relieved in 4 to 6 hrs. * the normal tissue pressure within closed compartments is approximately 0 mmHg > pressures of within 10 to 30mmHg of a patient’s diastolic blood pressure - there will be inadequate tissue perfusion and relative ischemia > if the pressure within a compartment equals or exceeds the patient’s diastolic blood pressure - there will be no effective tissue perfusion

Compartment syndromeASSESSMENT FINDINGS1. Pain- Deep, throbbing and UNRELIEVED by opioidsPain is due to reduction in the size of the muscle compartment by tight castPain is due to increased mass in the compartment by edema, swelling or hemorrhage

2. Paresthesia- burning or tingling sensation3. Numbness 4. Motor weakness5. Pulselessness, impaired capillary refill time and cyanotic skin6. Edema unrelieved by elevation

Compartment syndromeMedical and Nursing management1. Assess frequently the neurovascular status of the casted extremity2. Elevate the extremity above the level of the heart3. Assist in cast removal and FASCIOTOMY

Fat EmbolismOccurs usually in fractures of the long bonesFat globules may move into the blood stream because the marrow pressure is greater than capillary pressureFat globules occlude the small blood vessels of the lungs, brain kidneys and other organs

Onset of s/sx of fat embolism is rapid, (within 24-72 hours)

ASSESSMENT FINDINGS1. Sudden dyspnea and respiratory distress2. tachycardia3. Chest pain4. Crackles, wheezes and cough5. Petechial rashes over the chest, axilla and hard palate

Page 17: Emergency Nursing

Infection PreventionSilver sulfadiazine - bactericidal - minimal penetration to escharSilver Nitrate - bacteriostatic and fungicidal - does not penetrate escharMafenide acetate - Gram (-) and (+) -diffuses rapidly to eschar

Nursing Management1. Emergent phase (time of injury)Remove person from source of burn.1) Thermal: smother burn beginning with the head.2) Smoke inhalation: ensure patent airway.3) Chemical: remove clothing that contains chemical; lavage area with copious amounts of water.4) Electrical: note victim position, identify entry/exit routes, maintain airway.

Nursing Management1. Emergent phase (time of injury)Cool the burn for several minutes. DON’T USE ICE!!Wrap in dry, clean sheet or blanket to prevent further contamination of wound and provide warmth and conserve body heat.Assess how and when burn occurred.

Nursing Management1. Emergent phase (time of injury)Remove constricting clothes and jewelryCover the wound with a sterile dressing or clean, dry clothProvide IV route only if possibleTransport immediately to a hospital or burn facility

Nursing Management2. Resuscitative and Shock phase (first 24—48 hours)Provide appropriate fluid resuscitation based on the Parkland formula4 mL Plain LR x %TBSA of burns x kg body weightNursing Management3. Fluid remobilization or diuretic phase (2—5 days post burn)Monitor and treat potential complications like acute renal failure, paralytic ileus, Curling’s ulcer and hypokalemiaNursing Management4. Convalescent phasea. Starts when diuresis is completed and wound healing and coverage begin.

GENERAL NURSING INTERVENTIONS IN THE HOSPITAL1. Provide relief/control of pain.a. Administer morphine sulfate IV and monitor vital signs closely.b. Administer analgesics/narcotics 30 minutes before wound care.c. Position burned areas in proper alignment

GENERAL NURSING INTERVENTIONS IN THE HOSPITAL2. Monitor alterations in fluid and electrolyte balance.a. Assess for fluid shifts and electrolyte alterations b. Monitor Foley catheter output hourly (30 cc per hour desired).c. Weigh daily.d. Monitor circulation status regularly.e. Administer/monitor crystálloids/colloids

GENERAL NURSING INTERVENTIONS IN THE HOSPITAL3. Promote maximal nutritional status.

Page 18: Emergency Nursing

a. Monitor tube feedings if Peripheral Nutrition is ordered.NPO immediately after injury!!! ONLY when oral intake permitted, provide high-calorie, high-protein, high- carbohydrate diet with vitamin and mineral supplements.c. Serve small portions.d. Schedule wound care and other treatments at least 1 hour before meals.GENERAL NURSING INTERVENTIONS IN THE HOSPITAL4. Prevent wound infection.a. Place client in controlled sterile environment.b. Use hydrotherapy for no more than 30 minutes to prevent electrolyte loss.Observe wound for separation of eschar and cellulitis.GENERAL NURSING INTERVENTIONS IN THE HOSPITAL5. Prevent GI complications.a. Assess for signs and symptoms of paralytic ileus. b. Assist with insertion of NG tube to prevent/control Curling’s/stress ulcer; monitor patency/drainage.GENERAL NURSING INTERVENTIONS IN THE HOSPITAL5. Prevent GI complications.c. Administer prophylactic antacids through NG tube and/or IV cimetidine (Tagamet) or ranitidine (Zantac) (to prevent stress ulcer).d. Monitor bowel sounds.e. Test stools for occult blood.

RehabilitationMethods of coping and re-socializationEnsure optimum nutritionInitiate physical therapy to regain and maintain optimal range of motion and achieve wound coverage

Provide psychosocial support to promote mental health

RehabilitationProvide family-centered care to promote integrity of the family as a unitEncourage post-discharge follow-up for several yearsEnsure appropriate referral to cosmetic surgeon, psychiatrist, occupational therapist, nutritionist and physical therapist

Drugs for BurnsMafenide (Sulfamylon) 1) Administer analgesics 30 minutes before application.2) Monitor acid-base status and renal function studies. SIDE EFFECT: LACTIC ACIDOSIS3) Provide daily BATH for removal of previously applied cream.

Drugs for BurnsSilver sulfadiazine (Silvadene)1) Administer analgesics 30 minutes before application.2) Observe for and report hypersensitivity reactions (rash, itching)3) Store drug away from heat4) Disadvantage: poor eschar penetration

Drugs for BurnsSilver nitrate 1) Handle carefully; solution leaves a gray or black stain on skin, clothing, and utensils.2) Administer analgesic before application.3) Keep dressings wet with solution; dryness increases the concentration and causes precipitation of silver salts in the wound.

Page 19: Emergency Nursing

Drugs for BurnsPovidone-iodine (Betadine) Administer analgesics before application.Assess for metabolic acidosis/renal function

Gentamicin Assess vestibular/auditory and renal functions at regular intervals.

Cimetidine Given to prevent Curling’s ulcerWound debridement (ESCHAROTOMY)

Skin graftingAutograftHomograft - from living or recently deceasedHeterografts – from animalsBiosynthetic – biobraneDermal substitute – integra, allodermSkin Grafting

Don’ts in burnsDO NOT apply ointment, butter, ice, medications, fluffy cotton dressing, adhesive bandages, cream, oil spray, or any household remedy to a burn. This can interfere with proper healing. DO NOT allow the burn to become contaminated. Avoid breathing or coughing on the burned area. DO NOT disturb blisters or dead skin. DO NOT apply cold compresses and DO NOT immerse a severe burn in cold water. This can cause shock. DO NOT place a pillow under the victim's head if there is an airway burn and they are lying down. This can close the airway.

Commonly a metal support (stent) is inserted into the artery to help keep it open.A close up of a Stent.Angina Pectoris

NURSING MANAGEMENT1. Administer prescribed medicationsNitrates- to dilate the coronary arteriesAspirin- to prevent thrombus formationBeta-blockers- to reduce BP and HRCalcium-channel blockers- to dilate coronary artery and reduce vasospasmBasic Life Support This is a strategy which aims to improve the outcome for victims of Cardiopulmonary arrest and is now being adopted internationallyIt involves a series of events which are interconnected to each other like the links of a chain

HOW DOES CPR WORK?

All the living cells of our body need a steady supply of oxygen to keep us aliveCPR works because you can breathe air into the victim’s lungs to provide oxygen into the blood. Then, when you press on the chest, you move oxygen-carrying blood through the body.

WHEN WILL YOU DO CPR? CPR must be started as soon as possible when the carotid pulse is not appreciated or if breathing either stops or ineffective. In case of doubt, do CPR. Any delay in starting CPR reduces the chances of survival. In addition, the brain cells begin to die after four to six minutes without oxygen.
